The Rauk Heavy Tumbler is the meeting point of advanced digital design, inventive production techniques and the intimate whisky ritual.The glass has been developed for whisky drinkers who prefer their spirit chilled, whether with an ice sphere or simply on the rocks. And for those who revel in the crafted cocktail, the tumbler features a core innovation. Inside the glass lies an array of extruded chevrons radiating from the center, which serve to provide friction points for gripping ingredients used in muddled drinks. Circumventing the ornamentation of traditional cut crystal, the entire surface of the tumbler, inside and out, is born in a single blinding moment of machine-pressing the molten crystal into a complex five-part mold. The result is a pure expression of material and form that somehow feels not of this time, with geometric facets and edges blending organically into curved surfaces that fascinate the eyes and play with the sense of touch.
